Parameters

Return value

$node. The passed $node parameter should be modified as necessary and
returned so it can be properly presented. Nodes are prepared for display
by assembling a structured array, formatted as in the Form API, in
$node->content. As with Form API arrays, the #weight property can be
used to control the relative positions of added elements. After this
hook is invoked, node_view() calls field_attach_view() to add field
views to $node->content, and then invokes hook_node_view() and
hook_node_view_alter(), so if you want to affect the final
view of the node, you might consider implementing one of these hooks
instead.
